Klarna Checkout - Error in ExecutePayment

Hi!

We have problems with orders sometimes getting stuck in Init state. The order is there in Klarna backoffice, with status Reserved but missing Litium order id (reference). We get this in log:

2019-09-28 08:25:49.5910 [App:02] [c542e0f7-0868-4e50-b5b1-e0dda791f5c6] [DEBUG] [] Litium.Accelerator.Services.Payments.KlarnaPaymentService - Order created, order id c2e7a828-d0aa-4a12-9188-9a88f0bf7ace, external order id "LS213760".

   at Litium.Foundation.Modules.ECommerce.Payments.PaymentInfo.ExecutePayment(CheckoutFlowInfo checkoutFlowInfo, SecurityToken token)

The error must be for this row in KlarnaPaymentService.cs
var result = paymentInfo.ExecutePayment(checkoutFlowInfo, _securityToken);

After that we get this error in log, every four hours, trying to excute payment for order:

2019-09-28 12:25:48.8456 [App:02] [d0395033-45de-44fa-99a1-8a60036cf233] [DEBUG] [] Litium.Accelerator.Services.Payments.KlarnaPaymentService - Persisted order is found, order id c2e7a828-d0aa-4a12-9188-9a88f0bf7ace, external order id "LS213760".

Any idea of how to proceed with finding the cause for this problem? Not sure what method is not supported.

Litium version: 7.2.3

Upgrading to the latest version of the Klarna add-on, 4.7.104, released last week should resolve your problem. There was an issue getting the client language if the background call comes first which would result in the exception you’re seeing.
